    The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of coal according to the boiler demand and the amount of air available for drying and transporting the pulverized coal fuel is controlled by computers. Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizeralong with air heated to

  • Types of Boiler Coal Pulverizers Bright Hub Engineering

    Attrition TypeImpact and Attrition TypeImpact Or Hammer TypeThis type consists of a rotating shaft inside a stationary cylinder . The shaft contains arms that impact the coal inside the cylinder. The impact powders the coal. The hot air carries the coal to the burners. This is more suitable for softer coals with a higher Grindability index. Periodic replacement of hammers because of wear is a requirement. Another version of this in Lignite fired power plants.This is in the form of a fan and doubles as a fan and a mill. The impellers act as the hammers.
